Vida nerdgrrl is right, I went kayaking on the 28th post-op day. My OS had told me before surgery that I could start paddling and riding my bike after four weeks, but I was careful. I have 3 little boats, one 9.5 ft rec boat (Perception Swifty) that I keep on a rack right the lake behind my condo, and that's the one I used for the first paddle. It is a sit-inside with a large cockpit. A friend helped me get it into the water, about a foot deep, and I got in in the usual way---right leg first, sit down, pull left leg in. No problem. We paddled about 3 hours.
My next outing was with my 12 ft sit-on-top Hurricane Phoenix. This is by far the easiest type boat to enter and exit, especially in about a foot of water, just a matter of sitting down sideways and lifting legs in as you turn around.
The little boat in the picture is one of the sit-on-top Perception Tribes that belongs to the state park where I do volunteer work. Slow, stable, and very easy to enter and exit.
I also have a solo pack canoe, my favorite boat, which I've had out several times. A little more difficult to exit, as all weight must momentarily be placed on one foot, but it hasn't been a problem. (keep in mind also I had the anterior approach, so haven't had any worries about 90 degree flexion.) The canoe is the least comfortable to paddle right now----it is a pack canoe, seat on bottom, foot braces on sides and is paddled with a double blade paddle. The foot braces cause my feet to toe out slightly, which gets uncomfortable for my back and my hip, so I'm trying to figure out some way to modify that, or maybe it will just get more comfortable in time.
I was on the water (with the Phoenix) yesterday for about 6 hours with only two stretch breaks, and about half of the trip was paddling upstream against a headwind and current. I am achy this morning (hip and back) but I slept 8 hours straight last night.
Believe me, I understand that you are jonesing to get back in your kayak, but maybe you shouldn't do it while you're still using a cane, especially if you have a sea kayak with a keyhole cockpit, which I imagine you do, living in Vancouver. Or maybe if you had someone standing by to help. There's nothing like getting back to the things you love doing, to make you feel "normal" again
